Subject: [PATCH 11/29] vmlinux.lds.h: Replace RODATA with RO_DATA
Date: Thu, 26 Sep 2019 10:55:44 -0700 [thread overview]
Message-ID: <20190926175602.33098-12-keescook@chromium.org> (raw)
In-Reply-To: <20190926175602.33098-1-keescook@chromium.org>
There's no reason to keep the RODATA macro: just replace the callers
with the expected RO_DATA macro.
